johannes@sipsolutions.net 68970ce6ac [PATCH] softmac: handle iw_mode properly
Below patch allows using iw_mode auto with softmac. bcm43xx forces managed
so this bug wasn't noticed earlier, but this was one of the problems why
zd1211 didn't work earlier.

Seems we forgot to stop the queue while scanning. Better do that so we
don't transmit packets all the time during background scanning.

johannes@sipsolutions.net ba2f8c1875 [PATCH] softmac: return -EAGAIN from getscan while scanning
Below patch was developed after discussion with Daniel Drake who
mentioned to me that wireless tools expect an EAGAIN return from getscan
so that they can wait for the scan to finish before printing out the
results.

Michael Buesch 9b0b4d8ae8 [PATCH] softmac: fix spinlock recursion on reassoc
This fixes a spinlock recursion on receiving a reassoc request.

On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.

Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.

This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

Jean Tourrilhes c1783454a3 [PATCH] Revert NET_RADIO Kconfig title change
2.6.17-rc1 changed the title for the entry CONFIG_NET_RADIO. I
personally disagree with this change and want it reverted. Patch for
2.6.17-rc1.
	Rationale : WIRELESS_EXT is an invisible option. Therefore,
the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
	Rationale2 : the option just below is called "Wireless
Extension API over RtNetlink". Some users may confuse this option for
the main "Wireless Extension" option. Therefore reverting this change
help disambiguate the relation between those two options.

Dan Williams 6fcdf565ff [PATCH] wireless/airo: clean up WEXT association and scan events
Airo firmware versions >= 5.30.17 send re-association events to the
driver that are currently unrecognized, causing spurious disassociation
events to be sent to user space.  Loss of sync due to scan requests also
results in disassociation events sent to user space.  This patch traps
those two events; suppressing sync-loss on scan, and sending the correct
association event on re-association notifications.

must waiting for a long time.  After I check the "ULI M1573" south bridge

the Linux is "0xC7" not "0xC4" anymore So I was modified the source than it
was successed.

This patch removes all such inline and adds them to kprobes section
there by disallowing probes on all such routines.  Some of the routines
can even still be inlined, since these routines gets executed after the

  since APM is used very little on the Geode, and I have direct access to our

Tim Chen cca57c5b5a [PATCH] Kconfig.debug: Set DEBUG_MUTEX to off by default
DEBUG_MUTEX flag is on by default in current kernel configuration.

During performance testing, we saw mutex debug functions like
mutex_debug_check_no_locks_freed (called by kfree()) is expensive as it
goes through a global list of memory areas with mutex lock and do the
checking.  For benchmarks such as Volanomark and Hackbench, we have seen
more than 40% drop in performance on some platforms.  We suggest to set
DEBUG_MUTEX off by default.  Or at least do that later when we feel that
the mutex changes in the current code have stabilized.

Dipankar Sarma ca99c1da08 [PATCH] Fix file lookup without ref
There are places in the kernel where we look up files in fd tables and
access the file structure without holding refereces to the file.  So, we
need special care to avoid the race between looking up files in the fd
table and tearing down of the file in another CPU.  Otherwise, one might
see a NULL f_dentry or such torn down version of the file.  This patch
fixes those special places where such a race may happen.

Jeff Dike fb30d64568 [PATCH] uml: add missing __volatile__
We were missing __volatile__ on some bits of asm in the segfault handlers.
On x86_64, this was messing up the move from %rdx to uc because that was
moved to after the GET_FAULTINFO_FROM_SC, which changed %rdx.

Also changed the other bit of asm and the one in the i386 handler to
prevent any similar occurrences.

Rob Landley 966a082f80 [PATCH] uml: physical memory map file fixes
UML really wants shared memory semantics form its physical memory map file,
and the place for that is /dev/shm.  So move the default, and fix the error
messages to recognize that this value can be overridden.

Jeff Dike ad28e02978 [PATCH] uml: change sigjmp_buf to jmp_buf
Clean up the jmpbuf code.  Since softints, we no longer use sig_setjmp, so
the UML_SIGSETJMP wrapper now has a misleading name.  Also, I forgot to
change the buffers from sigjmp_buf to jmp_buf.

Hirokazu Takata 8e8ff02c0b [PATCH] m32r: Fix pt_regs for !COFNIG_ISA_DSP_LEVEL2 target
This modification is required to fix debugging function for m32r targets
with !CONFIG_ISA_DSP_LEVEL2, by unifying 'struct pt_regs' and 'struct
sigcontext' size for all M32R ISA.

Some m32r processor core with !CONFIG_ISA_DSP_LEVEL2 configuration has only
single accumulator a0 (ex.  VDEC2 core, M32102 core, etc.), the others with
CONFIG_ISA_DSP_LEVEL2 has two accumulators, a0 and a1.

This means there are two variations of thread context.  So far, we reduced
and changed stackframe size at a syscall for their context size.  However,
this causes a problem that a GDB for processors with CONFIG_ISA_DSP_LEVEL2
cannot be used for processors with !CONFIG_ISA_DSP_LEVEL2.

From the viewpoint of GDB support, we should reduce such variation of
stackframe size for simplicity.

In this patch, dummy members are added to 'struct pt_regs' and 'struct
sigcontext' to adjust their size for !CONFIG_ISA_DSP_LEVEL2.

This modification is also a one step for a GDB update in future.
Currently, on the m32r, GDB can access process's context by using ptrace
functions in a simple way of register by register access.  By unifying
stackframe size, we have a possibility to make use of ptrace functions of
not only a single register access but also block register access,
PTRACE_{GETREGS,PUTREGS}.

However, for this purpose, we might have to modify stackframe structure
some more; for example, PSW (processor status word) register should be
pre-processed before pushing to stack at a syscall, and so on.  In this
case, we must update carefully both kernel and GDB at a time...
